集束式潜孔锤

Cluster DTH hammer

【通用快捷，低成本，高效率】

1、集束锤采用标准方头连接

2、不同直径的集束潜孔锤的子锤和钻头通用

3、子锤小，拆装快，保养方便

 (universal, cost cut, efficiency )

1. Cluster adapts to standard square joints
2. Universal replacement of different size of hammer bits
3. Ease maintain of small hammer bit of cluster

【高效节能安全】

1、子锤冲频高，碎岩快

2、捞渣筒设计返渣好，减少重复破碎

3、子锤相互消除共振，对钻机、钻杆无损伤

 (efficiency, energy saving, safety)

1. High frequency, crushing fast
2. Flakes collector well circulate
3. Cluster hammer bit eliminate the shock resonance, safeguard the drill rod

【使用成本低】

1、子锤和钻头可以互换位置，均匀磨损，使用寿命长

2、与同等直径的单体锤相比，钻头便宜

 (low maintenance cost)

1. Replaceable of hammer bits for even wear out and longevity
2. Cluster hammer is cheaper than the individual hammer

【成孔质量好】

1、独特的配气设计，利于保持钻孔垂直

2、捞渣筒清渣彻底，孔底干净

3、可以在水下钻进成孔

(fine well quality of hole)

1. Unique air DTH hammer design for hole straightness
2. Powerful flakes collector for cleaning hole bottom
3. Workable under water for piling

集束式潜孔锤，解决了潜孔锤入岩施工的高成本，高能耗的问题

广州振宇机械结合韩国，美国等国的先进的入岩技术研发的大直径集束式潜孔锤，实现了潜孔锤低成本，高效率，使得大口径潜孔锤的普及应用成为可能

时间2016年10月

地点：海南儋州恒大项目

地质条件：粘土，回填，中风化

入岩15米，桩长25米

集束式潜孔锤与整体式潜孔锤的对比：

入岩速度，集束式的快过整体式的，

磨损：由于集束式的潜孔锤可以任意更换互换小锤头而磨损很少，而且不会整体报废。整体式的，一个标段要用2台。

能耗：集束式的风压要求不高，从而，节能。

Cluster DTH hammer solve the problem of high cost energy consumption in DTH drilling

Combined with the advance technology of korea and US, designed by zhenyu the large diameter cluster DTH hammer make it possible to drill in low cost running and great productivity.

Time: October 2016,

Location: evergrande project in Danzhou Hainan,

Geology formation: clay, backfill, medium weathering layer

Depth of drilling hole: 25 meters, depth of rock excavation: 15 meters.

Cluster DTH hammer versus individual DTH hammer:

Comparison: penetration rate of cluster hammer is faster than integral hammer ,

Wearing: cluster hammer less wear out became of replaceable cluster hammer bit comparing to integral hammer bit which can wear out 2 units in a single tender.

Energy consumption: cluster DTH hammer has less energy consumption because of low air compression request.

Conclusion: cluster DTH hammer more efficiency, greater productivity and profitability.
